Only four years after leading the Chicago White Sox to the World Series championship, Fielder Jones was enlisted to coach the OAC baseball team. A salary dispute with Sox owner Charles Comiskey led to Jones' departure from the Windy City and he came to the Pacific Northwest to look after timber and land interests. Coach Jones traveled back and forth between Portland and Corvallis for team practices and games. Jones eventually went to St. Louis to coach the city's entry in the Federal League in 1914 and 1915. He was also coach of the American League St Louis Browns from 1916-1918
Frederick Mitchell Walker was head coach in 1911. Walker pitched for five different teams in the major leagues in 1910, and 1912-1915. He was known as "Mysterious Walker" in his playing days.
